R. W. GROTH SWING Filed Sept. 28, 1961 April 28, 1964 United StatesPatent O 3,130,969 SWING Roderick W. Groth, 624 NE. 3rd, Camas, Wash.Filed Sept. 28, 1961, Ser. No. 141,408 1 Claim. (Cl. 272-85) Thisinvention relates generally to amusement apparatus for children, andmore specifically to a novel type of swing construction.

It is a primary object of this invention to provide an apparatus forexercise and amusement which comprises a circular seat or swing boardwhich is supported in a horizontal plane by diametrically opposed ropeswhich extend upwardly to form an apex by which the seat is supported.

lt is another object of this invention to provide a novel swingstructure which is capable of holding several children and may beoperated to swing in any direction, gyrate in an arcuate motion, ormerely rotate about its central axis.

Yet another object of the invention is to provide a sturdy swingstructure which may be used as a conventional swing, or may be caused togyrate in new and interesting patterns hitherto unobtainable in theconventional swing.

A still further object of the invention is to provide a swing structurefor children which may be simultaneously enjoyed by a number of childrenat one time.

A full understanding of the construction of this invention, togetherwith further novel features and advantages, will be had from thefollowing detailed description of a preferred embodiment thereof, takenin conjunction with the attached drawings wherein:

FIG. 1 is a perspective view of the apparatus and associated supportframe structure.

FIG. 2 is a side elevation of the swing structure supported in amultiple swing mounting.

FiG. 3 is a cross sectional side elevation taken through the circularseat and showing the peripheral rubber bumper surrounding the same toprovide added safety for those playing on the apparatus.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring now to the drawings in detail, the numeral 5 represents a atcircular disc or seat which may be provided with an outwardly projectingperipheral rib 6 for the purpose of mounting a semi-circular bumper pad7. The bumper pad may be molded in rubber and is provided with a groove8 formed centrally of its inner side for engagement over the rib 6. Theseat may be made of plywood or other suitable material and is supportedby means of four eye bolts 9 which are disposed at an equally spacedmanner adjacent the periphery of the disc. Four equal lengths of chainor rope 10 are secured at one end to the eye bolts 9 and extend upwardlyto terminate in the ring 11 of a common supporting eye bolt 12. The eyebolt 12 is secured such that it will project vertically from a suitablesupport structure. A ceiling beam, a bough of a tree, or a supportframework are given as examples of the type of support which 6 may besuitably utilized for this purpose.

In FIG. 1, of the drawings, the eye bolt is shown extending centrallythrough the horizontal plate 13 and may be rigidly locked with respectthereto, or may be permitted to rotate about a vertical axis accordingto preference. The plate 13 terminates at each corner with fourdownwardly extending tubular sleeves 14 which lockingly engage fourdownwardly extending arms 15. Each. of the arms terminates in an elbow16 which is mounted cross bar through suitable elbows 21 and shorttubular arms 22. 'I'he apparatus is supported intermediate each of thepairs of legs by the eye bolts 12 which extend radially through thecross bar 20 and are secured in position by means of suitable washers 23and threaded nuts 24.

The dimensions of the apparatus are of course a matter of choice, thoughit is intended that the seat should be in the order of three feet indiameter so as to be capable of supporting up to six children at onetime. The versatility of the apparatus will be quite apparent to thereader since there is no limitation with respect to direction ofmovement or rotation, and combinations of such movements may readily beaccomplished by children either standing or seated around the seatperiphery.

Having described the invention with considerable particularity, itshould be understood that various modifications may be made to theprecise detail thereof, without departing from the scope or spirit ofthe invention as defined in the appended claim.

I claim:

An amusement apparatus for children comprising, in combination, a ilatcircular seat, a plurality of support ropes of equal length extendingfrom the periphery of the seat and terminating at a common supportingeye bolt, said eye bolt being secured beneath a structure to support theseat for arcuate and pivotal movement relative thereto, said eye boltbeing rigidly mounted beneath said structure, said structure comprisinga horizontal rectangular plate supported by tubular arms and legsextending downwardly from each corner of said rectangular plate, and tierods extending horizontally between the upper ends of the legs forming arectangular frame to maintain said legs in a ixed relation with respectto each other.
